I've had a Nexus One, an HD2, and an iPhone. I still like Windows mobile for some things:

Zuma

Experiment 13

Office Mobile (I know there are Android alternatives, but IMO nothing as good)

smooth as hell on a 1ghz snapdragon.

More UI customizations and lockscreens, although Android is coming along very well in that department.

Better Emulators (ATM)

a couple more things maybe.

Android, on the other hand offers

more/better apps,

less resource hog,

LWPs (I love me some LWPs)

update your ROM without a hard reset

continued developers and app support

more than 1 device running on a snapdragon/hummingbird

many many more features.

For me the HD2 is the perfect device. I have an awesome/stable/sweet 6.5 ROM and I can load up an awesome/stable/sweet Android 2.2 ROM with new builds coming out daily. I can benchmark from 1500-1900 depending on my ROM, build, and settings and OC to 1190 mhz. There is much development on Android for the HD2, we have awesome ROMs where literally EVERYTHING works (my current sense UI 2.2 ROM has no bugs at all), we have a full CM6 port, just needs some bugs tweaked.

Any time I want to play Zuma or get on office mobile or get a new WinMo ROM flashed I can do that too. I think I'll stick with my HD2 WinMo/Android rig till something AWESOME comes out.
